In the fields of industrial control, medical equipment, and telecommunications infrastructure, based on Intel ®  Core ™ The ATX motherboard of platform 2 is still in service in a large number of critical systems due to its mature PCI ecosystem, rich I/O interfaces, and stable driver support. The M-322 launched by ADLINK adopts Intel technology ®  Q35+ICH9DO chipset, supporting LGA775 packaged Core ™ 2 Quad/Duo, Pentium Dual Core, and Celeron processors, providing 6 SATA 3Gb/s ports (supporting RAID 0/1/5/10), 12 USB 2.0 ports, dual gigabit network cards, 1 PCIe x16, 1 PCIe x1, and 5 PCI slots. It also integrates TPM security chips and programmable watchdog timers, making it an ideal choice for upgrading old systems and quickly deploying new projects. This article will provide engineers with a complete practical guide from the perspectives of model selection, hardware layout, jumper configuration, BIOS tuning, and system resource allocation.

Product positioning and CPU selection strategy

M-322 adopts the standard ATX board type (305mm × 244mm) and is designed for applications such as automation control, testing and measurement, and security monitoring. The core highlight lies in:

CPU compatibility: Supports LGA775 processors with Intel Yorkfield/Wolfdale/Conroe architecture, including Core ™ 2 Quad Q9400 (2.66GHz/1333MHz FSB/6MB cache) Core ™ 2 Duo E8400（3.0GHz/1333MHz FSB）、E7400（2.8GHz/1066MHz FSB）、E6400、E4300， As well as Pentium E5300/E2160 and Celeron 440, TDP covers 35W~95W, and should be selected reasonably according to the heat dissipation conditions.

Chipset: Intel Q35 GMCH+ICH9DO, supports DMI bus connection to CPU, integrates GMA 3100 display core (400MHz, supports DirectX 9, maximum shared 256MB of video memory).

Memory: 4 240 pin DDR2 DIMM slots, dual channel 667/800MHz, maximum 8GB (non ECC, non buffering module required).

Expansion slots: 1 x PCIe x16 (Gen1), 1 x PCIe x1, 5 x PCI 2.2, meeting the requirements of traditional data acquisition cards and motion control cards.

Storage: 6 x SATA 3Gb/s, supports RAID 0/1/5/10 (Intel Matrix Storage), with 1 IDE (PATA) interface and 1 FDD interface.

I/O intensive: rear 4 x USB 2.0, 2 x PS/2, 1 x VGA, 1 x COM (DB9), dual RJ-45, 3 x audio; The board provides 8 x USB 2.0 pin sockets, 3 x RS-232 pin sockets (COM2-4, where COM4 can switch RS232/422/485), 1 x LPT parallel port, 1 x GPIO (20 pins), 1 x SPI, 1 x S/PDIF, etc.

Security features: Onboard Infineon SLB 9635 TT 1.2 TPM chip, supporting hardware level key storage and encryption.

Selection suggestion: If you need quad core performance and good chassis heat dissipation, choose Q9400 (95W); If power consumption is sensitive, choose E8400 (65W) or Celeron 440 (35W). If virtualization support is required, please note that Core2 Duo/Quad supports VT-x, but some Pentium models do not.

Detailed jumper settings (key configurations)

3.1 Clearing CMOS (CLRTC)

Default 1-2 short circuit (normal).

Clear CMOS: After power off, move the jumper cap to 2-3, hold for 5 seconds, then move it back to 1-2, and power on again. This operation can reset the BIOS password and all settings.

3.2 COM Port Power Supply Selection (JCOMPWR1~4)

The 9th pin (RI) of each COM port (1-4) can be configured as no output,+5V, or+12V to power external serial devices (such as barcode scanners). JCOMPWR1 corresponds to COM1, JCOMPWR2 corresponds to COM2, and so on. Jumper settings:

1-2 Short circuit:+5V

2-3 Short circuit:+12V

Default no jumper (RI signal)

3.3 COM4 mode selection (RS232/422/485) - JCOMPWR5, 6, 7

COM4 is the only port that supports three modes, set through three sets of jumper combinations:

Mode JCOMPWR5 JCOMPWR6 JCOMPWR7

RS232 (default) Short circuit 1-2 Short circuit 1-2 Short circuit 1-2

RS422 short circuit 3-4 short circuit 3-4 short circuit

RS485 Short Circuit 5-6 Short Circuit 5-6 Short Circuit 5-6

Note: In RS422/485 mode, the DB9 pin function of COM4 becomes a differential pair (TXD+/TXD -, RXD+/RXD -), as shown in Table 2-1 of the manual. RS485 mode supports multi station bus, but attention should be paid to terminal resistance matching (not built-in on the motherboard, external addition is required).

Detailed explanation of BIOS key settings (based on AMI BIOS)

System resource and interrupt allocation

5.1 Memory Mapping

The traditional ISA area (768K~1MB) is reserved, and some areas are allocated to VGA BIOS, PXE Option ROM, etc. If installing more than 4GB of memory, Memory Remap needs to be enabled.

5.2 I/O Address

COM1-4 fixed addresses (3F8/2F8/3E8/2E8) correspond to IRQ4/3/10/11 (adjustable) respectively.

LPT1 defaults to 378h/IRQ7.

SATA controllers, USB UHCI/EHCI, SMBus, etc. are dynamically allocated by BIOS.

5.3 IRQ Allocation (APIC Mode)

Interruptions 16~23 are caused by PCIe devices USB、SATA、 Network card sharing, please refer to Appendix B Table B-6 for details. When installing a PCI card, if there is a conflict, you can try replacing the PCI slot (different slots have different INT lines).

5.4 PCI configuration space

Built in devices (VGA, USB, SATA, network card, etc.) have fixed bus/device numbers, PCIe to PCI bridge (ICH9DO connects to PCIe to PCI bridge) to connect PCI slots, and resources are automatically allocated by BIOS.

Watchdog Timer Configuration (WDT)

M-322 integrated watchdog, based on Super I/O (W83627DHG-A), programmed through I/O ports. Appendix A provides sample code (unlocking Super I/O, selecting logical device 8, setting timeout mode (seconds/minute) and count value, and then resetting the counter by rewriting it). In industrial applications, "Watchdog Timer (seconds)" can be directly enabled in the BIOS and a timeout value (such as 60 seconds) can be set. After the system starts, WDT will automatically run. If the OS or application is not refreshed in time, it will trigger a hardware reset, greatly improving the system's self-healing ability.

Key points for driver installation and RAID configuration

7.1 Driver installation sequence

Install operating systems such as Windows XP/7/Server 2008.

Install the Intel Chipset Driver.

Install display driver (GMA 3100).

Install the network card driver (Realtek RTL8111C).

Install the audio driver (ALC888).

Install TPM driver (if required).

If RAID is enabled, press F6 to load the Intel Matrix Storage driver (simulated using a floppy disk or USB drive) during OS installation.

7.2 RAID Configuration

Set 'Configure SATA as' to RAID in BIOS.

After booting up, press Ctrl+I to enter the Intel RAID configuration interface and create RAID volumes (0/1/5/10).

Load drivers when installing the OS.

Common troubleshooting

Fault 1: No display when powered on

Check if the 4-pin CPU power supply is connected; Try a single memory and swap slots; Clear CMOS.

Confirm that the CPU is LGA775 and the FSB matches the motherboard (800/1066/1333MHz).

Fault 2: SATA hard drive not recognized or blue screen (0x7B)

If the AHCI/RAID driver is not loaded during OS installation, temporarily set it to IDE mode in BIOS to enter, and then inject the driver or reinstall it.

Check the SATA data cable and power cable, and try replacing the SATA port.

Fault 3: Communication abnormality of COM4 RS422/485

Confirm that jumper JCOMPWR5-7 is correctly set to the corresponding mode.

Check the wiring of external devices (TXD+/TXD -, RXD+/RXD -), paying attention to common ground.

A 120 Ω terminal resistor needs to be added at the beginning and end of the RS485 bus.

Fault 4: GPIO has no output

Confirm that the power supply of JDIO pin (pin 20+5V) is normal and the software configuration direction is correct (requiring the use of GPIO registers for Super I/O).

Fault 5: Network wake-up (WOL) is invalid

The "Onboard LAN Boot" option in BIOS and the Wake on LAN related option (such as Resume On PME #) in APM need to be enabled.

Power supply+5VSB needs to provide at least 1A.

Fault 6: System time loss

Replace the CR2032 button battery on the motherboard.

Maintenance and spare parts recommendations

Heat dissipation: It is recommended to use the recommended copper core heat sink (115 × 115 × 61.4mm, 4500RPM) to ensure that the inlet air temperature of the chassis does not exceed 60 ℃.

Firmware update: Use AMI Flash tool to update BIOS, pay attention to backing up the original files.

Spare parts: The Q35/ICH9DO platform has gradually been discontinued. It is recommended to reserve key chips (such as Super I/O, network cards) or spare boards.
